This property depends on the size and on the construction of the molecular particles that compose the panels. The wood conglomerate absorbs much more moisture and water compared to calcium sulphate. X-floor, by contrast, is totally non-absorbent.
This is the capability to interrupt the frequency of sounds transmitted through the materials.
N.B.: Noise reduction capability is heavily dependant on the type of concrete slab onto which the raised flooring will be installed.
The capability of calcium sulphate is good thanks to its compact and uniform structure. Despite the fact that the density of wood conglomerate is half that of calcium sulphate, it has a slightly better reduction capability, due to its physical composition. Lastly, X-floor is between the two.
It should be noted that the possibility of raised floor resonance effects is strictly related to the morphology and architectural peculiarities of the building itself.
Thanks to their bending resistance even under large loads, panels with calcium sulphate and X-floor cores ensure excellent comfort underfoot. Conversely, under an equal load, wood conglomerate panels manifest more flexibility and elasticity.
Reaction to fire, meaning the degree of participation of a flammable material in a fire to which it is subjected. Resistance to fire is the predisposition of a construction element to preserve the stability required, over a certain period. Calcium sulphate is made up of inert mineral materials, which do not participate in combustion. The same is true for X-floor, made of an atomised mixture of clays, kaolins and feldspars. A chipboard core reacts participating in combustion.
